i dont know the length of yj springs but i believe they are a lil longer and they are wider. i guess if they are the same length you could use washers or something to make up the difference in width on the cj springs at the shackle and springeye. you would have a gap between your spring and the ubolts at the springplate that would scare me a lil.
ok, now why would you want to? cj springs dont flex as well and arent as stable as yj springs.
